Internet SIG Directions, Craig Thompson, ISIG co-chair
We had a brief discussion on the need for new directions for Internet SIG
and decided to hold a brainstorming session at the Denver meeting and to
include a review of the results of the Internet
Services RFI as a started set of possible new actions. Many of those
have since been adopted but many have not so let's triage these and see
what else is still needed.
Computer Supported Cooperative Work (CSCW) Working Group, Henry Rothkopf,
A version 2 of the CSCW
green paper (internet/00-01-02) is now available. It drops away some
DoD references and uses an OMG example. Jeff
Kurtz (MITRE) led a review of this green paper.
Critical things to do by next meeting
Other important things to do
determine relationship to Task and Session, Workflow, Negotiation, ECTF
Collaboration, and maybe Knowledge Management especially. Enterprise Application
determine if and when we will do a CSCW RFP - complete a draft by Denver
focusing on section 6 using new
standard rfp template
explicitly separate collaboration meaning from UML collaboration diagrams,
EC collaboration, and CSCW collaboration
consider interoperability among collaborative workspaces but maybe explain
why not to consider it in an RFP
should CSCW stay under Internet SIG or move nearer to workflow and task
areas like role and policy are under specified
Discussion on Issues
Policy discussion notes. There are many broad interests in
OMG onpolicy. One short description - policy is the behavior of the system
as supported by the system developer and controlled by the owner. Policies
for allocation and shared resources are at server and behavior of how to
display to user is at client. (But not always).
Related work on policies: Morris Slowman in England has been working
on policy languages. Are policies consistent. Security policy languages
like Detail++. Work by Greg S, Doug Maughm. Policy Languages as in
Polar Sudan's. Telco is working on network management. Paul Kaitv
from Rogue Wave.
OMG needs a general Policy Management Green Paper. How broad a framework
do you want? Enterprise uses. Perceived issues of control and management.
Policy is a statement of business rules. It provides roles and responsibility,
rules, enforcement, authority to do X on data Y. Define the set of
roles and their duties and what sorts of framework variables can be controlled
(by mechanisms that support the policy choices). What are the administrative
tasks. Use cases of administration of these activities. Must be dynamic
because people's roles change on an immediate basis. One thesis is to allocate
tasks by role and when you start doing a task then you get a new role.
Dynamic assignment and reassignment.
Composing in other Services. How to add the CSCW framework
into workflow, security, e-commerce, and task and session. How does QoS
Observation: OMG does not have a good language and set of interfaces
for fully describing composition in terms of being able to introspect on
interfaces and implementations to see how a thing is composed and how to
replace modules or insert new behaviors. This is a big hole.
workflow and task and session are (perhaps) super and sub sets of CSCW
and we want some interconsistency
security can be interlaced in several ways, via security unaware or where
each object is supported. What kind and when do you need non-repudiation.
Possibly many ways to do this.
not sure how EC negotiation fits except that collaboration participants
might want to negotiate among themselves or possibly with outsiders. And
the EC may have frameworks for people and sessions that are relevant.
